Question

At my current database i use date format yyyy-mm-dd.
If i want to search by DOB then must use format yyyy-mm-dd to match it with default date format.

Is there a way to search DOB from whatever user input wether its dd-mm-yyyy or dd/mm/yyyy or yyyy-mm-dd and give out the result???

$keyword = clean($keyword,1);

$result = $db->query("SELECT name, dob, email FROM user WHERE name LIKE '$keyword%' OR dob LIKE '$keyword%' OR email LIKE '$keyword%'");

if($result){
   //echoing the result
}

Not easily. First convert the user input to the correct format before passing it to the SQL query.

For example:

if (preg_match('~([0-9]{2})[-/]([0-9]{2})[-/]([0-9]{4})~', $input, $matches)) {
    return $matches[3].'-'.$matches[2].'-'.$matches[1];
} else {
    return $input;
}
